ISAAC GLINE, OF HUNTINGTON, INDIANA.

BRAGE FOR CROSS-ARMS OF TELEGRAPH AND TELEPHONE POLES.

To all whom it may concern:

Be it known that I, ISAAC CLINE, a citizen of the United States,residing at Huntington, in the county of Huntington and State ofIndiana, have invented certain new and useful Improvements in Braces forCross- Arms of Telegraph and Telephone Poles; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to new and useful improvements in braces for thecross arms of telegraph and telephone poles and my object is to providefor reinforcing or strengthening the said cross arms and thereby greatlyprolonging the usefulness thereof.

Other objects and advantages will be hereinafter made clearly apparent,reference being had to the accompanying drawings made a part of thisapplication, and in which,

Figure 1 shows a side elevation of my invention as applied to use uponan ordinary telegraph or telephone pole. Fig. 2 is a top plan view ofFig. 1, while, Fig. 3 is a sectional View on line 33, of Fig. 2.

Referring in detail to the various parts of my invention and also tocooperating adjuncts, 1 indicates the telephone or telegraph pole of theusual or any preferred construction, while 2 designates the cross arm,also of the usual or preferred pattern, 3 indicating the insulatorsready to receive the wires.

Upon the inner side of the cross arm 2, I mount my reinforcing orbracing member consisting preferably of three parts as the middleportion 4 and the outer members 5 and 6, the hinge members beingdesignated by the numeral 7. The central member 4: is provided with anopening, through which an anchoring bolt 8 is entered, said bolt passingentirely through the telegraph pole and the cross arm 2, as shown inFig. 2. I provide the hinges 7 so that my improved brace may be readilyapplied to its operative position without reference to the size of thepole, it being understood that the outer ends of the members 5 and 6 arepermanently anchored in union with the outer Specification of LettersPatent.

ends of the cross arm, as indicated by the bolts 9.

In order to strengthen the members i, 5 and 6, I prefer to provide uponone or both edges thereof, the flange 10, as shown in Fig. 3, thusmaking it possible to use a minimum amount of material in theconstruction of said braces.

In applying my improved brace to use, all that is necessary is to enterthe bolt or bolts 8 in position and then force the outer ends of themembers 5 and 6 in engagement with the outer ends and inner side of thecross arm 2, when a hole of proper size may be bored through said crossarm and the bolt 9 entered therein, it being understood that suitableapertures have already been formed in the outer ends of said members 5and 6.

By the use of my bracing appliance, the severe strain upon the cross arm2 is reduced to a minimum and distributed so that there will be noliability of breaking said cross arm, as is now common. It is thought,therefore, that the importance and value of my improved brace and itscapacity to accommodate itself to cross arms and poles of any size, willthus be made clearly apparent, and further description is deemedunnecessary.

IVhat I claim is 1. The combination with a pole and a straight crossarm, of a bracing member formed in sections, said sections beinghingedly secured together and extending horizontally, means to attachthe bracing member and cross arm to the pole and means to attach theends of the bracing member to the cross arm.

2. The combination with a pole and a straight cross arm, of a bracingmember consisting of a horizontal middle and two horizontal outersections, means to hinge said sections together, means to secure themiddle member and cross arm to the pole and additional means to securethe free ends of the outer sections to the cross arm.

3. The combination with a pole and a straight solid cross arm, of ahorizontal middle section parallel with the cross arm and two horizontalouter sections at an angle with the cross arm to brace the latteragainst the strain exerted by Wires carried In testimony whereof I havesigned my by said arm said sections being of L-shaped name to thisspecification in the presence of form in cross section, hinges securingthe two subscribing Witnesses. outer sections to the middlesection,means to ISAAC CLINE.

5 attach the bracing member and cross arm to the pole and means toattach the ends of the bracing member to the cross arm.
